D++ (DPP)
C++ Discord API Bot Library
Using component interactions (buttons)

Discord's newest features support sending buttons alongside messages, which when clicked by the user trigger an interaction which is routed by D++ as an on_button_click event. To make use of this, use code as in this example.

#include <dpp/dpp.h>
#include <iostream>
#include <dpp/message.h>
int main()
{
dpp::cluster bot("token");
/* Message handler to look for a command called !button */
bot.on_message_create([&bot](const dpp::message_create_t & event) {
if (event.msg->content == "!button") {
/* Create a message containing an action row, and a button within the action row. */
bot.message_create(
dpp::message(event.msg->channel_id, "this text has buttons").add_component(
dpp::component().add_component(
dpp::component().set_label("Click me!").
set_type(dpp::cot_button).
set_emoji(u8"😄").
set_style(dpp::cos_danger).
set_id("myid")
)
)
);
}
});
/* When a user clicks your button, the on_button_click event will fire,
* containing the custom_id you defined in your button.
*/
bot.on_button_click([&bot](const dpp::button_click_t & event) {
/* Button clicks are still interactions, and must be replied to in some form to
* prevent the "this interaction has failed" message from Discord to the user.
*/
event.reply(dpp::ir_channel_message_with_source, "You clicked: " + event.custom_id);
});
bot.start(false);
return 0;
}
The cluster class represents a group of shards and a command queue for sending and receiving commands...

When the feature is functioning, the code below will produce buttons on the reply message like in the image below:
